This paper addresses range-spread target detection in spherically invariant random vector clutter.The modified detector based on scatterer density dependent (MSDD) is introduced
and the formula relating false alarm probability to detection threshold is deduced.It shows that MSDD performs best when the target energy is uniformly distributed in range cells;moreover
it is also robust for various target range extent.However
when the estimated number of scatterers is smaller than the actual one
MSDD is degraded sharply.To improve the robustness of MSDD
a detector with dynamic threshold (DT) is proposed.For DT
the dynamic estimated number of target scatterers is adjusted according to the observations
which can improve performance and robustness of detector effectively.
